Because of the problem with diff and G9 firmware dumps noted here:
http://chdk.setepontos.com/index.php/topic,288.msg8614.html#msg8614, I've spent some time examining hexdumps -- and found a problem.
It looks very much like ewavr's
udumper (
http://chdk.setepontos.com/index.php/topic,745.msg6166.html#msg6166) cuts off before the end of the G9's firmware.
Titan_G9's blinker dump has data and code from 0x00000000 to 0x00330B68, then FF's through 0x005DFFFF. Code and data start again at 0x005E0000 and continue in blocks through 0x007EA59B.
In both my (
udumper) dump and bingo_bongo's (corrected for leading zeroes), the FF's begin at 0x00330BD8 and continue through 0x003FFFFF -- but then there are 00's from 0x00400000 through the end of the dump.
The
udumper dump is missing a lot of code -- probably the IS routines, and certainly the language tables. The disassembled code looks good to me -- but what do I know. Help, anyone?
